The bugs from 1.16.20 have pretty much returned and they are even worse than they were before, plus with many other bugs, but I'll tell the main one that is so annoying and makes the game nearly unplayable.

So Imagine opening up any kind of UI on your screen (menu, chest UI, chat, etc...)

Expected results: The UI opens up normally, nothing wrong happens.

The current results: Sometimes (can happen anytime, like right after launching the game, when you've been playing for a while, or anytime in between), a loading screen appears as if it is having connection issues and this even happens when on a single player world.

This makes the game close to impossible to play, so please fix this, As I am probably not the only one mad about this.
